Interval.
Bakura is trapped inside a dark rehab of his own mind, lost in lust and memory's while trying to forget by trapping himself in the dark. After going through the room with Ryou and smoking joint after joint (how long is unknown by Bakura counted the accumilated events; 389), his conciousness kicks in and makes him realise that isn't making things better, instead of wallowing in his own repatitive mind and abusing his body by killing his heart, body and brain cells with all the cannabis he's been smoking, he should be going to get what he wants. Ryou.

But only two things stand in the way. The voice, which he isn't sure if it's his own or something much worse, and the minescule fact he doesn't know where Ryou is.
All he does know is they have him.

I know who has Ryou, Bakura.
Who?

Uh-uh, I'm not that easy, I know you are but-
Shut up and tell me where he is!
Hahaha! Go pay Mr. Seto a visit. It's been so long, I think a nice family reunion is in order.
